Installation notes for Micro-C:

0) Update to (at least) Micro-C v3.15!

1) Micro-C does not support include search paths, therefore you must
put all files from ..\..\INCLUDE into your Micro-C directory.
As well as this "external.h".

2) You may just copy COMPILE.* into the up-updir and run COMPILE.BAT.

3) Update your <stdio.h> file by adding Micro-C's version number to
the _MICROC_ macro, add:
#define _MICROC_ 0x314
